Please reference which distro you’re commenting on.

In RHEL 5, “blacklist” is a modprobe directive that may be included in /etc/modprobe.conf.

Hence, adding the following to /etc/modprobe.conf:

blacklist ipv6

will result in the ipv6 module NOT loading at boot time.

@ harmonica goldfish
Permission denied means you need to change permissions or use an account with more privileges.
Type the following at the command prompt to learn more:
man su
man chmod

And ‘blacklist’ is not a command, it’s a configuration file.

cd /etc/modprobe.d
pico blacklist

And add this line at the end (or wherever):
blacklist ipv6

Write out and you are done. If you have a ‘blacklist’ config file in your /etc/modprobe.d directory, adding that line is the easiest way to make ipv6 go away until you are ready for it.

On LinuxMint Daryna kernel 2.6.22-14-generic
I opened /etc/modprobe.d/aliases w/kate – replaced “ivp6″ with “off” – saved – closed.
Just as this article instructs & now no more Gazillions of “ivp6″ entries in the syslog.

You should use a text editor to make changes to that file. joe, vim, etc.
Also you can use MC also to easily navigate and edit (F4) the file. HTH.

I am trying to replace the line mentioned in the original post. I am in terminal, I have my list of aliases…how do I actually replace it? It seems to be un-editable?

I am a newbie and it took me a while to figure out how to even get the list to display…this is what I did.

I also tried the blacklist thing, as you can see in the results, with no luck.

thanks for any guidance!

Hello all,

at least on a recent Debian System you can disable your undesired modules by adding them to /etc/modprobe.d/blacklist.

For example to disable IPv6 just add a line like:
